Then analysis was done by injecting a 1 ll aliquot in a splitless mode into a Hewlett Packard 6890 gas chromatograph (Avondale, PA, USA) equipped with a flame-ionization detector and a DB-5 fused-silica capillary column (30 m 0:32 mm i.d.; film thickness 1 lm; J&W Scientific, Folsom, CA, USA). Injector and detector temperatures were set at 300 C. Oven initiating temperature was at 190 C, elevated to 215 C at 6 C/min, and then increased up to 300 C at 32 C/min, held for 3 min. Nitrogen was used as a carrier gas. The percentage yield (percent weight conversion) was defined as ðmg biodiesel mg initial soybean oilÞ 100% and was estimated using peak area integrated by on-line software Hewlett-Packard 3365 Series II ChemStation (Avondale, PA, USA). 摘自------ 期刊:Bioresource Technology 88 (2003) 103–106 文章题目:Optimization of lipase-catalyzed biodiesel by response surface methodology 自己看看吧,呵呵 |
